Description
Fliehkraftkupplung Bei Fliehkraftkupplungen ist es entgegen den oft geäußertenAnsichten nicht erwünscht, daß bei auftretender Überlast eine Entkupplung bzw. ein Gleiten eintritt. Da andererseits das beim Anlauf übertragbare Drehmoment die Anlaufstromstärke bedingt, so ist es erforderlich, nachträglich eine Steigerung dieses Drehmomentes bis auf das Kippdrehmoment durchzuführen. Ferner ist es auch unzweckmäßig, die Kupplung plötzlich mit dem vollen Anlaufdrehmoment vorzunehmen. Man hat nun bereits mit der einen Welle umlaufende Fliehkörper in einem mit der anderen Welle verbundenen, zum Teil mit 01 gefüllten Gehäuse angebracht, derart, daß sich die Reibflächen an Fliehkörpern und Gehäuse bei Stillstand und langsamem Umlauf mit Öl benetzten, bei steigender Umlaufzahl die Fliehgewichte zunächst an geschmierten Flächen anlegen, sodann das Öl durch Druck der Gewichte und Fliehkraft nach außen in einen ringförmigen Kanal außerhalb der Reibflächen gepreßt wurde. Da das 01 infolge seiner Dünnflüssigkeit ziemlich schnell aus den Reibflächen entfernt wird, verwendet die vorliegende Erfindung zum Schmieren das starrere Schmierfett und sorgt durch besondere Vorkehrungen dafür, daß die Reibflächen bei erneutem Anlauf wieder gut eingefettet sind.Centrifugal clutch In centrifugal clutches, contrary to what is often said, it is not desirable for a decoupling or slipping to occur when an overload occurs. On the other hand, since the torque that can be transmitted during start-up determines the start-up current strength, it is necessary to subsequently increase this torque up to the breakdown torque. Furthermore, it is also inexpedient to make the coupling suddenly with the full starting torque. It has now, already mounted with a shaft rotating centrifugal elements in a connected to the other shaft part with 01 filled housing, such that the friction surfaces of Fliehkörpern and housing during standstill and low speed circulation is wetted with oil, with increasing winding number the flyweights first place it on lubricated surfaces, then the oil was pressed outwards into an annular channel outside the friction surfaces by the pressure of the weights and centrifugal force. Since the 01 is removed rather quickly from the friction surfaces due to its low viscosity, the present invention uses the rigid grease for lubricating and, through special precautions to ensure that the friction surfaces are well greased again upon renewed start.
Ein Ausführungsbeispiel zeigen Abb. z und 2 der Zeichnung. Die Riemenscheibe ist nach Abb. 2 außen mit Rillen z versehen. In diese hinein wird nach erfolgtem Ansprechen der Kupplungsgewichte 2 das Fett 4 gedrückt. Sobald die Gewichte 2 und .3 wieder abfallen, wird die Bürste 5 vorgeschoben. Diese holt das Fett aus den Rillen r heraus und läßt es seitlich ablaufen (s. Abb. 2), so daß es wieder auf die Reibfläche kommt. Die Abbildungen stellen natürlich nur beispielsweise Anordnungen dar.An exemplary embodiment is shown in Figs. Z and 2 of the drawing. The pulley is provided with grooves z on the outside as shown in Fig. 2. Into this one becomes after what has been done When the clutch weights 2 respond, the grease 4 is pressed. As soon as the weights 2 and .3 fall off again, the brush 5 is advanced. This gets the fat out of the Grooves r out and lets it run off to the side (see Fig. 2), so that it comes back on the friction surface comes. The figures are of course only examples of arrangements represent.
